1. A method of diagnosis of traumatic brain injury comprising the steps of:

  • providing a head mounted goggle based stimulus generating eye tracking unit to the subject;

    presenting visual stimulus to the subject, wherein the visual stimulus is in the head mounted goggle based system and forms the optical target stimulus for at least two distinct tests including at least two of nystagmus tests, smooth pursuit tests, saccades tests, optokinetic tests, subjective visual horizontal and subjective visual vertical;

    obtaining objective physiologic response of the subject from the head mounted goggle unit based upon each of the visual stimulus presented to the subject in each test; and

    using the objective physiologic responses to diagnose the presence of traumatic brain injury.
